[0118] Further, refer to figure 1 , the second embodiment of the NAS attachment system of the present invention provides a NAS attachment system, based on the above-mentioned first embodiment of the NAS attachment system of the present invention, the MME21 is also used for,

[0119] Obtain the security capability information of the UE10 according to the security mode request; judge whether the security capability of the MME21 matches the security capability of the UE10; if the security capability of the MME21 matches the security capability of the UE10, then Corresponding configuration security algorithm.

[0120] When configuring the security algorithm, the MME21 obtains the security capability information of the UE10 recorded in the security mode request, including all encryption algorithms and integrity algorithms supported by the UE10.

[0121] Then, MME21 searches for the same encryption algorithm supported by UE10 according to the preconfigured encryption algorithm supp...

Abstract

The invention discloses an NAS attach system. The NAS attach system comprises user equipment UE and a core network. The UE is sued for initiating an attach request to the core network. The core network is used for verifying the attach request and issuing attach process signaling to the UE if verification of the attach request is passed. The UE is also used for performing network authentication on the core network according to the attach process signaling. If network authentication of the core network is passed, attach complete signaling is fed back to the core network. The invention also discloses an NAS attach method. NAS attach flow redundancy can be greatly reduced and time of the UE for registering to the core network can be saved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a NAS attachment system and method. Background technique [0002] NAS (Non-access stratum, non-access stratum) exists in the wireless communication protocol stack of UMTS (Universal MobileTelecommunications System, universal mobile communication system), as a functional layer between the core network and UE (User Equipment, user equipment), This layer supports signaling and data transfer between the two. [0003] However, the current NAS layer attach (attach) process of LTE (Long Term Evolution, long-term evolution technology) network and the like is cumbersome, requiring a large amount of signaling interaction between the UE and the core network. For example, UE needs to go through Attachrequest (attachment request), Identity request and response (identity request and response), Authentication request and response (authentication request and response), security a...
